Virus Alert! in Toolbar - HJT included

I have the Virus Alert! message in my toolbar and other random places around my computer, typically where there should be an AM or PM on a time. I am pretty sure I received it after downloading a media codec last night. Thanks for any help that you all can provide.

Open the SmitfraudFix folder and double-click smitfraudfix.cmd
Select option #1 - Search by typing 1 and press "Enter"; a text file will appear, which lists infected files (if present).
Please copy/paste the content of that report into your next reply.

Note : process.exe is detected by some antivirus programs (AntiVir, Dr.Web, Kaspersky) as a "RiskTool"; it is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.http://www.beyondlogic.org/consulting/proc...processutil.htm

You should print out these instructions, or copy them to a Notepad file for reading while in Safe Mode, because you will not be able to connect to the Internet to read from this site.

Please reboot your computer in Safe Mode by doing the following :

Restart your computer

After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;

Instead of Windows loading as normal, a menu with options should appear;

Select the first option, to run Windows in Safe Mode, then press "Enter".

Choose your usual account.

Once in Safe Mode, open the SmitfraudFix folder again and double-click smitfraudfix.cmd
Select option #2 - Clean by typing 2 and press "Enter" to delete infected files.

You will be prompted : "Registry cleaning - Do you want to clean the registry ?"; answer "Yes" by typing Y and press "Enter" in order to remove the Desktop background and clean registry keys associated with the infection.

The tool will now check if wininet.dll is infected. You may be prompted to replace the infected file (if found); answer "Yes" by typing Y and press "Enter".

The tool may need to restart your computer to finish the cleaning process; if it doesn't, please restart anyway into normal Windows. A text file will appear onscreen, with results from the cleaning process; please copy/paste the content of that report into your next reply along with a new HijackThis log.
The report can also be found at the root of the system drive, usually at C:\rapport.txt

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure to checkmark the Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

Make sure that you restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

Currently, my computer seems to be much better. The Virus Alert! message is gone and everything seems pretty much normal. It seems to take a bit longer to boot now, but I don't have numerous popups anytime I try to move the mouse.

I did try to fix O24 like you said but it is still there after running the log.

Renaming Hijackthis comes in handy particularly for some (Vundo) infections as they look for that file name. Unless the name is changed, you are unable to see either the 02 entries or the 020 entries.
